T 0 all whom it mo 1 concern:

Be it known that I, RICHARD PIIILLIPs, a

citizen of the United States, residing at ashington, in the District of (olumbia, have invented certain new and useful Improvements in Trolley-Retrievers, of which the following is a specification. I

This invention relates to improvements in .trolley retrievers or finders.

The main object of the present invention is to provide a means adapted to be in proper position for operation at all times independwire.

A'I'Iothcr object is to provide a means which is automatically thrown into and out of operative position without any attention on the part of the conductor.

The preferred details of construction of the present invention will be described in the f olowing specification, reference being had particularly to the accompanying drawing in which z- Figure 1 is aside elevation of my im proved trolley retriever: Fig. 2 is a plan view of the same: Fig. 3 is a rear elevation, Fig. 4 is a verwith the trolley wheel omitted: Fig. 5 1s a similar sectional view showing the V guide thrown to upright or operative position.

Referring particularly to the drawing, 1 is the ordinary trolley pole harp; 2 is the trolley Wheel, and is mounted.

In the preferred form of my device the. pin is extended slightly beyond the arms of the harp. On the extended ends of the pin 3 is pivotally mounted a frame 4. At the rear of the frame is a V shapedguide 5 which is pivotally mounted on the same by means of the in 6, said pin being securely attached to the lades of the guide 5 and free to turn in the frame 4. A coil spring 7 attached at one end to the guide, and at the other to the frame, tends to force the guide to an upright position as shown in Fig. 5. The guide however is normally locked in a l'iorizontal position by the double armed catch 8, which engages one of the-arms of said guide. The catch 8 is pivoted on the stud t) and carries the coil spring 10 which forces the catch into engagement with one arm of the gu' le. Mo unted upon the upper edges of theframe 4 are two lovers 11, 11, pivoted to the. frame by four lugs 12, said levers having at their forward ends transversely extending notched 3 is the pin on which the. wheel arms 13, which arms are slightly curved and l l l l y. l l l and the diverging arms of adapted to contact with the feed 'wire when the wheel flies off. At the rear ends of levers 11 are downwardly and inwardly extending arms 14, 15, adapted to bear against the lower and u catch 8.

Upon a stud 16 carried on one of the inner sides of the fran e 4 is a small lever 17, and upon the adjacgnt arm of the guide 5 is a downwardly ex ending arm 18 adapted to strike one side of the upper arm 26 of the lever 17, and at substantially a right angle to arm 18 is an arm 24 adapted to strike the other side of arm 26. Stop 20 prevents arm 26 from swinging too far back, and a spring 19 presses said arm in the direction of said stop. in front of lower arm of lever 17 is a sliding bolt 21, which is pressed against said lever arm by a spring 22. The forward end of bolt 21 is brought to an edge and adapted to engage ratchet teeth 22% cut on the cry of one of the arms of harp 1.

ltigidlyattached to frame 4 at the juncture with the pin 3 are two downwardly and for- -wardly suspended weights 25. These weights are held by screw threads so that they Inay be adjusted to varying heights. 1. have found that when the weights are projected somewhat in advance of the vertical passing through the pin the action is most satisfactory although the device would be operative were they same.

The operation of lows: The guide the invention is as fol- 5 is normally locked in the horizontal position on the frame 4, but when the trolley slips from the feed wire and flies upwardly beside tl strikes the wire and this actuates one of the. rear arms 14 or 15 of the bent lever 11, which in turn presses on the catch 8 and causes it to release the guide 5. The guide is then forced to an upright position by the spring 7, i the guide serve to guide the trolley hack to the feed wire. As the guide assumes the upright position the integral arm 18 which has been bearing on the lever 17 moves away from the same and allows the spring 19 to force the bolt 21 into engagement with the teeth 23 on the. harp 1 and thereby lock the frame 4- so that it cannotv swing downwardly. As the guide coinpletes its upright movement the arm 24 strikes the upper arm 26 of lever 17 thereby preventing the guide from swinging too far in this direction, and also more securely suspended directly below the is same, one of the arms13 periphsition, 'means' for automatical forcing the bolt 21 into locking engagement with the teeth on the harp arm. When the trolley passes below a cross wire or other ohstruction, the guide is returned to the hori- 1. In a trolley retriever, a swinging frame,

meansmounted in sockets on said frame for contacting with the feed wire when the trol-' ley is thrown upwardly, means for engaging the wire to direct the trolley wheel back again to the same, said contacting means actuating said engaging means to throw the same into operative position.

2. In combination, a trolley pole, a harp formed on said ole, a trolley retriever having a swinging rame ivotally mounted in said harp, and a v-sraped guide, means automatically actuated to place said guide in operative position when the trolley is itlhrown upward and lock the frame to the arp.

3. In a swinging trolley retriever, means for engaging the feed wire means for locking said wire engaging means in inoperative poy releasing said en agin means, and means for automatic al y re coking said engaging means when the same is forced under a cross wire.

4. In combination, a trolley pole, a harp formed on said pole, a trolley retriever having a pivotall mounted frame, means to automatically ock said frame to the harp of the pole when the trolley flies off, and means to relieve the same when the retriever has passed under a cross wire.

5. In a trolley retriever, a swinging frame weighted to a horizontal position, means for engaging the feed wire to return the wheel when the same flies off, said means being normally locked in me erative position, means to automatically tfirow the engaging means into 0 erative position, a trolley harp, means to 100 the frame to the trolley harp while the engaging means is inoperative position, and to release the frame when passed under'a cross wire. j I 6. In a trolley retriever, a harp, a pin passing through said harp and he 0nd the arms of the same, a wheel carrif b said pin, a frame pivotally mounted .on tv e extended ends of said pin, a V shaped guide pivotally mounted at the rear of said frame, and a weight suspended from and rigidly attached to said frame at the point of uneture with said pin.

7. Ina trol ey retriever, .a harp, a pin svassa' passing through said harp and beyond the arms of the same, a wheel carried b said pin, a frame pivotally mounted on t e extended ends of said pin, a V 'sha ed guide pivotally mounted at rear of said 'rame, resilient means for forcing said guide to an upright position, and a weight suspended from ant rigidly attached to said frame at the point of uncture with said pin.
